There is so much confusion in the marketplace about liposuction, mostly because of marketing claims. There are 3 things to consider: who is best qualified to do it, where is it best to have it done, and what is the best technology/technique. Since liposuction is surgery, you should ask carefully about your plastic surgeon's qualifications and experience. And all plastic surgery, including liposuction, should be done in a fully accredited surgical facility. Finally, remember that it is the surgeon, not the technology that makes the biggest difference in your outcome. Laser lipo (smart lipo and others) has been hyped to the extreme, often with frankly incorrect statements such as enhanced safety. The potential benefits of adding the laser to the lipo procedure are highly debatable but since the laser can cause burns and tissue damage it has an inherently greater risk.
As for Sonobello, all I know is that here in Washington State they have had at least one well-publicized death following a laser lipo procedure, and there are something like 2 dozen complaints with the medical board under investigation.
